Realsense Camera D435 with different imaging lenses

[Wgao6]

I have Realsense D435 camera, but the View is big for us.

I changed both lenses for left and right infrared image sensor from 1.93mm to 3.8mm effective focal length.

I captured images through realsense-view and did intrinsic calibration by Matlab script, and write back the calibration result to D435

through CustomRW -w CalibrationParameters.xml command.

but when I run camera at 1280x800 resolution, it shows hardware problem, and 640x480 no problem, but almost no depth matching point.

Is there a limit in D435 processing card that limit the Focal length left and right value away from the original 1.93mm (643.3 pixels)?

You can do hardware sync with the D435 now, yes. On the D435 model, you can only sync depth streams (the D415 can sync both color and depth streams). This is because the D415 has its RGB sensor integrated on its circuit board, but the D435 has the RGB sensor attached separately.
